Nigel Farage, leader of Reform UK, has been interviewed by the standards commissioner regarding a £5m gift from crypto billionaire Christopher Harborne, the Sunday Times reported.

The interview lasted approximately half an hour and focused on whether Farage was required to declare the money under parliamentary rules. Farage has stated the gift was intended for his personal security.

The investigation examines potential breaches of parliamentary standards. Farage holds a seat in the House of Commons as an MP, placing him under the jurisdiction of the Parliamentary Commissioner for Standards.

The source of the funds and the circumstances of the gift raise questions about transparency in political finances. The commissioner's inquiry will determine whether Farage's handling of the money complied with the parliamentary code of conduct, which requires MPs to register financial interests above certain thresholds.

Harborne, described as a crypto billionaire, is the source of the disputed payment. The nature of his business interests and any prior relationship with Farage remain unclear from the available information.

The outcome of the standards commissioner's investigation could result in findings of misconduct, sanctions, or clearance of any wrongdoing. The process typically includes questioning of the subject and review of relevant documentation before the commissioner issues a report with conclusions.
